WHEEL-MOUNTING.

Application filed December 17, 1314. Serial No. 877,749.

To all whom it may, concern:

Be it known that l, SAMUEL F. McBRinn, a citizen of the United States,residing at Birmingham, in the county of Jefierson and State of Alabama,have invented certain new and useful Improvements in Wheel- Mountings,of which the following is a spec-- ification, reference being had to theaccompanying drawings.

My invention relates to bearings, and particularly to bearings forvehicle wheels.

The primary object of my invention is the provision of a hearing soconstructed that the bearing is entirely housed within the hub 01" thewheel, thus preventing dust and dirt from gettinginto the bearing andeconomizing oil, and is further so constructed that the wheel may turneasily upon a vertical axis to permit the wheel to be shifted forsteering, its steering axis being disposed also entirely within the hubof the wheel.

A further object is to provide foigthe ready disassembling of the partsor the ready assembling of the parts. or for the remoral of the wheeland for the adjustment oi' the anti-iriction bearings disposed withinthe hub.

Other objects will appear in the course of the following description.

My invention is illustrated in the acconr an viu; drawings, whereinFigure lv is a. section on the line '11 of Fig. l .2 is a section on theline 2-2 'lig. is a section on the r oi Figs. 1 and line 3 5 of Fig. l.Corresponding and like parts are referred to in the followingdescription and design natcd in all parts of the accompanying drawingsby like reference numerals.

Referring to these drawings. 2 designates a shaft, and 3. the axle whichforms a housr int! tor the shait. The sha t '2 at pposite culls isformed with the arms -l and with a partly spherical recess 5. Disposedwithin this recess 5 and hetwcen thc arms 4- is the ball 3 of aiuiivcrsal joint. Pills l'cxtcnd inward from the arms l. and ihc taperedends of thesipins cuter sochcts h foruicd in diametrically opposite por.ms of the hall 6. The hub end of thc hal'i. l is dcsip'uatcd S). and isalso toruual at its inner end with an eulargcd head l having a concaverccess 11 in its end. within which a portion of the hall lils.

arms are disposed in a plane at right angles -to the arms l. Pins 13extend inward from the arms 1:2, and-'the tapered ends of these pins fitin the sockets formed in diametrically opposite portions of the ball 6.It will thus be seen that I provide a universal joint between the mainportion of the driving shaft 2 and the hub portion 9, thereby permittingthe hub portion 9 to turn angularly with respect to the main portion 2,but caus' Surrounding the end of the axle or hous ing' 3 is an annularbearing ring designated 15. The inner face of this bearing ring istransversely straight, while its outer face is provided upon its lateralmargins with the inclined roller engaging faces 16. This ring 15 at oposite points in its diameter has pins 17 w rich are driven into the endsof the housing 3, these pins having their axes coincident with the planeof the axes of the pins 7 and forming pivots upon which the bearing ring15v may turn in a horizontal plane.

Mounted upon the reduced end of the shaft section 9 and rotatabletherewith is a.

hub cap 18 which is preferably keyed t0 the shaft extension 9. This hubcap is formed with the inwardly extending flange 19, the outer face of.which is inclined outward and toward the middle of the shaft 2.

Disposed upon this flange and fitting snugly therett is the hub 20 towhich the spokes 20 are connected in any suitable manner. The inner faceof this hub 20 is howled to fit the bevel of the exterior face ot theflange 19. and preferably the hub is the flange 19 at its inner whichare beveled'and confront the beveled thein'terior screw threads faces ofthe ring 15, and disposed between the cones 2? and the beveled iaces'goithe bearingring 15' are the tapered ill'llZl-ZllltlllOIl' rollers 28.The annular bearing ring l5-is interiorly screw threaded 'at one end asat 29, and disposed within the nut 23 is an annulus 30 having ,at itsinner end the inwardly extending flange 31 which is exteriorly screwthreaded for engagement with Where the wheel is to be used as asteeringwheel, this annulus 30'is formed with the angularly extending arm 32,which in turn is connected with the usual steering knuckle and steeringrod of the automobile or other vehicle. The annulus 30 is formed with ashoulder 33 which bears against the packing 26. Shims or liners 34 arepreferablydisposed between the end of the innermost cone 27 and the nut23, so that as the nut is turned the cone 2? on thatside will beadjusted inward into the hub. This of course will tighten up upon theroller hearings on that side. The rotation of the annulus 30 will alsocause the transverse adjustment of the bearing ring 15, which willadjust the roller hearings on the opposite'side or outer end of the hub.A packing ring 35 carried by the annulus 30 and having an inner beveled.face surrounds and bears against the enlarged head of the axle 3 and maybe ad usted against this head by rotating the annulus 30. j

The operation of my invention will be ob vious from what has gonebefore.v The hub as constructed provides for free rotation of the wheelin a horizontal plane as well as a rotation of the wheel in a verticalplane.

The pivotal axis upon which the wheel rotates for steering movement isdisposed in a plane which coincides with the vertical plane of the wheelrim, thus relieving the wheel of the strains to which it is incidentwhen the steering axis is disposed exteriorly of the wheel as isordinarily the case. The parts of-the wheel may be read-i'lykept tightso as to take up wear, the partsare all entirely housed within the hub,and it is impossible for dust to have access to the in terior of the hubby reason of the fact that the packing ring 35 bears tightly against theenlarged head of the axle.

My invention is applicable to all manner of vehicle wheels, butparticularly applicable to the wheels of automobiles and like vehicles.I

Having described my invention, what I I claim is:

the cones and the margins of the bearing rings, an annular nut havingscrew thread-' ed engagement with the inner end ot the hub and bearingagainst the inner end ot the cap flange, and shims disposed between saidnut and'the inner end of the adjacent cone. 2. In a wheel mounting, ahollow axle having a hollow enlarged end, a shaft housed within the axleandhaving a main section and'an end section connected by a. universaljoint, an annular bearing ring surrounding the enlarged head of theaxle, pivot pins passing through said bearing ring and into said headand being coincident with the pivotal axis of the universal joint, saidbearing ring having beveled lateral margins, a hub cap mounted upon androtatable with the end section of the shaft and having an inwardlyextending flange, a hub engaging with said flange but projecting beyondit at'its end and internally screw threaded at this end, cones disposedwithin the inwardly extending flange of the cap, tapered anti-frictionro'llers disposed between the cones and the beveled margins of the ring,an annular nut having'serew threaded engagement with the screw threadson the hub and bearing against the end of the flange, shims disposedbetween said nut and the adjacent cones, a packing ring carried on theinner face of the nut, a packing ring extending around the head of theaxle and disposed against the head and an annulus having a flangeexteriorly screw threaded to engage screw threads 011 the inner face ofthe bearin ring. the end of said flange carrying sai last named packingring, the outer face of the annulus bearing against the packing ringcarried by the nut.

3. -In.-a wheel mounting, an axle, an annular bearing ring pivotallymounted on the axle for horizontal. movement, a. hub cap having aninwardly extending flange surrounding the bearing ring, a hubsurrounding the cap and resting thereon, anti-friction cones and rollersdisposed between the bearing ring and the flange of the cap, an annularnut having screw threaded engagemen'twith the hub, and an annular memberhaving screw threaded engagement withthe bearing ring andoperativelyengaging with the nut to lock it in place.

4. In a, wheel mounting, an axle, an annular bearing ring pivotallymounted tl1oreon for movement in a horizontal plane, a

hub cap having an inwardly extending l .fiange formed with a bevelediperiphery, a

" rollers disposed between the bearing ring and the cap flange, anannular nutihaving screw threaded engagement with the hub, an annularmember having screw threaded engagement with the bearing ring, said nutand member having complementary con-- 10 fronting recesses, and apacking ring dis-' posed in said recesses. it

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
